当前,电力供应紧缺是国民经济发展中一个相当突出的薄弱环节,重点产煤县感受尤深。一方面,由于电力供应不足,大部分煤矿难以按常规组织生产,生产力受到一定制约;另一方面,由于不断拉闸限电,井下安全作业没有保证。有些煤矿为保证井下安全的起码电源,不得不自备柴油机组,以油换电,但所花代价太大,柴油发电每度4～5角,煤矿难以承受。因此,发挥本县煤炭资源优势,就地自办坑口电站,把煤与电有机地结合起来,走以煤保电、以电养煤、煤电 At present, the shortage of power supply is a rather prominent weak link in the development of the national economy. The key coal producing counties feel particularly deep. On the one hand, due to the lack of electricity supply, most coal mines are difficult to produce as conventional ones and their productivity is restricted. On the other hand, there is no guarantee of safety in underground operations due to constant power cuts. Some coal mines in order to ensure the safety of underground power at least, had its own diesel engine to oil for electricity, but the cost is too large, diesel power generation per degree 4 ~ 5 angle, unbearable coal. Therefore, to play the advantages of the county’s coal resources, local self-pit mine power station, the organic combination of coal and electricity, take the coal to power and electricity to raise coal, coal
